What are Probiotics for Dogs?

“Probiotics are living microorganisms which when administered in adequate amounts confer a health benefit on the host” – this definition from the World Health Organization depicts the true nature of probiotics and their tribute to health.

Basically, the dog‘s digestive system is inhabited by billions of microorganisms – primarily bacteria but also yeasts. Some of them are good, and others are potential pathogens. Together these microorganisms are collectively called the microbiome, and under normal circumstances, they are in balance.

Sadly, many conditions and medications can throw this balance out of order for your dog. This is where probiotics for dogs prove beneficial. They support the growth of good bacteria and prevent the potential pathogens from overgrowing and compromising digestive health and overall wellbeing.

Are Probiotics Safe for Dogs? 

Yes, probiotics are perfectly safe for dogs. Using probiotics for your dog can help promote healthy bacteria and strengthen their immune system. It’s important to use high-quality pet-specific probiotics for your dog to ensure their efficiency and safety.

Do Probiotics for Dogs Need Prebiotics?

Yes, probiotics for dogs need prebiotics. 

Probiotics work better when used together with prebiotics. Prebiotics or dietary fiber serves as food for the good bacteria, thus helping them grow and exert their beneficial effects. One of the simplest and best source of prebiotics for dogs is pumpkin. 

What are the Benefits of Probiotics for Dogs?

The benefits of probiotics for dogs are diverse and promising. Depending on the strains of bacteria included in the product, probiotics for dogs can help with the following:

  • GI tract health and improved digestion. Probiotics for dogs help manage and prevent various digestive tract issues, improve the digestion processes, absorption of nutrients, and vitamin synthesis.
  • Better stool quality. Probiotics for dogs are the ideal anti-diarrhea supplements as they reduce both their duration and intensity. They can even reduce or eliminate the need for antibiotics for diarrhea management.
  • Decreased risk of intestinal worms. Studies suggest that probiotics for dogs can be used to control hookworm infestations and are currently studied to examine their effect on other parasites.
  • Oral health and better breath. Certain probiotic strains help prevent common oral issues, and others have proven antimicrobial effects. This leads to better oral hygiene and prevents bad breath.
  • Stronger immune system. Probiotics for dogs have powerful immune-boosting features. When given to pregnant dogs, they can increase the immune power of the colostrum.
  • Skin issues and allergies. Probiotics for dogs offer a novel perspective for managing dermatological conditions. They can relieve the symptoms linked with food allergies and atopic dermatitis.
  • Ear infections. Probiotics for dogs can help with ear infections because they release anti-inflammatory substances and can relieve skin itchiness.
  • Better mood and relaxation. The presence of a gut-brain axis gave birth to the so-called behavioral probiotics or specific strains of bacteria that can improve the dog’s mood and prevent anxiety issues.

Do Vets Recommend Probiotics for Dogs?

Yes, vets recommend probiotics for dogs. 

Here is what Dr. Walker, DVM says: “Yes, probiotics are recommended for dogs. I particularly recommend probiotics when there is a gastrointestinal disturbance, such as diarrhea secondary to eating something that they should not have, to reestablish normal/healthy gastrointestinal flora (bacteria).

I recommend Honest Paws Pre+Probiotic because it comes in powder packages with chicken flavors that are usually palatable to canines and easy to add to each meal. I recommend using them once a day for 5 consecutive days if there is a GI disturbance, but they could be used daily long term in patients that have sensitive gastrointestinal tract.

When Should You Give Your Dog Probiotics?

You can give probiotics to dogs when there is an ongoing imbalance in the gut microbiome or preventively before the imbalance occurs. In other terms, you should give your dog probiotics in the scenarios listed below:

  • There are gastrointestinal issues that can benefit from good bacteria
  • If your pup has diarrhea or you suspect it will develop it soon
  • In the case of allergy-triggered skin issues and ear infections
  • When the dog’s immune system needs a healthy and natural boost
  • During long-term use of antibiotics.

What Time of Day Should I Give My Dog Probiotics?

Ideally, you should give your dog probiotics early in the morning before breakfast. 

While there is no rule about the timing, most experts believe it is best to give probiotics in the morning because, at this time, there is the least amount of gastric acid in the dog’s stomach. This means the bacteria’s travel to the intestines will be safer. 

However, veterinarians agree that consistent use of probiotics is more important than following a strict dosing schedule.    

How Long Should a Dog Take a Probiotic?

The length of the use of probiotics depends on the dog’s overall health and the underlying condition.  Some dogs need occasional supplementation (using probiotics on an as-needed basis), while others benefit from continuous use of probiotics. 

If you are not sure whether you should discontinue the use of probiotics, it is best to consult with your trusted veterinarian

What are the Types of Probiotics for Dogs?

Which probiotics for dogs are best for your pup depends on its unique needs. Different probiotic strains come with different health perks. Therefore, it might be best to get a formula that involves various strains of probiotics for dogs, including some of the following:

  • Enterococcus faecium helps manage stress-triggered diarrhea and has an immune-stimulating effect in young pups (protects from common pathogens like Escherichia coli and Salmonella).
  • Bifidobacterium animalis supports a healthy gut and intestines and is perfect for managing idiopathic canine diarrhea. It also helps dogs recover after prolonged use of antibiotics.
  • Lactobacillus casei has strong anti-inflammatory properties and a proven bactericidal effect against potential pathogens. It is also beneficial for mood improvement.
  • Lactobacillus rhamnosus provides immune support, helps manage food and skin allergies and their symptoms, and prevents unwanted yeast overgrowth.
  • Lactobacillus plantarum is a highly resistant microorganism that survives the conditions in the dog’s digestive system, manages diarrhea, and promotes liver health.
  • Lactobacillus acidophilus supports the digestive system on various levels and helps with dermatitis symptoms and managing allergic reactions to food.
  • Lactobacillus fermentum has an inhibitory effect on certain bad bacteria and provides symptomatic relief from urinary infections and various gastrointestinal issues.
  • Bacillus coagulans is a spore-forming bacterium that helps with different forms of diarrhea, including traveler’s and antibiotic-triggered. By forming spores, it protects the lining of the intestines.
  • Saccharomyces boulardii is a healthy yeast robust for managing chronic enteropathies and antibiotic-triggered diarrhea. It also has immune-boosting features.

What Should I Look for in Probiotics for Dogs?

When choosing probiotics for dogs there are several things to consider. Here is a closer look at those factors: 

  • Bacteria Strains. The first thing is to check the type of bacteria in the supplement. Some probiotics for dogs have one and others have several different strains of beneficial bacteria. 
  • Colony Forming Units (CFUs). CFUs measure the number of beneficial bacteria in the supplement. In general, the higher the CFU of the supplement, the better its quality. 
  • Added Ingredients. In addition to good bacteria, some probiotic supplements feature added ingredients such as prebiotics or dietary fiber, fatty acids, antioxidants, vitamins, and minerals. 
  • Supplement Form. Probiotics for dogs come in different forms such as powders, capsules, liquids, and edibles (chews). You should get the type that is easiest to give. 
  • Probiotic Flavor. To ensure straightforward use, manufacturers add flavors to the dog probiotics. Popular flavors are bacon, beef, and chicken. Choose the flavor your dog likes best. 
  • Brand. Finally, pay attention to the probiotic brand. A trustworthy brand will be open about its ingredients and practices. It will also feature reviews from previous customers. 

Are Human Probiotics the Same as Dog Probiotics?

No, human probiotics for dogs are not the same as dog probiotics.

The main differences between human and dog probiotics are the type of bacteria and the number of live bacteria. This is becuase the dog’s gut bacteria is different than the human’s.

Specific probiotics or bacterial strains are present in both dogs and humans. However, they will be present in much higher numbers (colony forming units – CFU) in the human supplement than they would be in dog probiotics.

Another difference is in the added ingredients. Namely, human probiotics often feature ingredients that are harmful to dogs. Human supplements may contain xylitol – an artificial sweetener that is toxic to dogs.

Can Dogs Take Human Probiotics?

Yes, dogs can take human probiotics as long as they do not contain ingredients that are dangerous to dogs. However, when it comes to human probiotics for dogs, they are not as effective as dog probiotics. 

Probiotics are beneficial bacteria that help maintain a healthy gut and GI tract. They can help with health issues like constipation, diarrhea, bloating, obesity, and bad breath.

Other benefits of probiotics for dogs also include adequate digestive tract function, strengthened immune system, and reduced stress. 

To ensure these benefits, your dog needs the right probiotic. Supporting gut health and preventing digestive issues is harder if using human probiotics for dogs instead of dog probiotics.

What’s the Difference Between Human-Grade Probiotics and Human Probiotics for Dogs?

Human-grade probiotics are dog probiotics made with high-quality ingredients or ingredients that pass all the requirements for human consumption. Generally speaking, the best probiotics for dogs are made with human-grade ingredients.

On the other hand, human probiotics are supplements formulated explicitly for humans. They have good bacteria that are specific to the human GI tract and digestive health.

In simple words, the main difference between human-grade probiotics and human probiotics is in the type of probiotics (healthy microbes) within the supplement.

What are the Side Effects of Probiotics for Dogs?

According to a 2010 study, “Safety and Tolerance of Dietary Supplementation With a Canine-Derived Probiotic (Bifidobacterium animalis Strain AHC7) Fed to Growing Dogs,” probiotics for dogs are “well tolerated with no safety concerns.”

However, same as any other supplement, they can cause side effects in overly sensitive pets. Luckily, the side effects are mild and transient and usually revolve around GI tract upsets – loose stool or constipation, bloating, and gassiness.

The chances of developing side effects are higher when introducing new strains or switching probiotic brands. Side effects are also more likely to occur if the supplementation includes high doses, sudden implementation, and low-quality probiotics for dogs.

Can a Dog Have too Much Probiotics?

Simply put, dogs cannot overdose on probiotics as they do not contain directly troublesome ingredients. This is because ingesting higher amounts of probiotics is not directly harmful or toxic. However, too many good bacteria can upset the dog’s digestive system and cause issues like diarrhea and excessive gassiness.   

Worst-case scenario, dogs that eat too much probiotics will develop mils and transient digestive issues in the form of stomach upset – diarrhea, vomiting, gassiness, and bloating. 

How Much Probiotics Should I Give My Dog a Day?

According to Joseph J. Wakshlag, DVM, PhD from the Cornell University, dogs need between 1 and 10 billion CFUs of probiotics per day.

However, the exact amount depends on the dog’s body weight, overall health, and the underlying reason for using probiotics. While some dogs benefit from regular, daily use of probiotics, others do well with occasional supplementation. 

Before using probiotics for dogs, read the instructions and dosage guidelines on the package. If unsure, consult with your trusted veterinarian. 

How can I Give My Dog Probiotics?

First of all, we should note that some commercial dog food formulas contain added probiotics. However, if your dog needs an additional boost, the number of live cultures in the dog food is not enough.

In such cases, you need to consider probiotics for dogs in the form of supplements. Luckily, there are different forms of probiotics for dogs – powders, capsules, liquids, soft chews, and treats. This gives you the freedom to choose which option is best for you and your pup.

You can also use some natural sources of probiotics for dogs like yogurt and kefir. For optimal results, add a supplement product to your dog’s regimen and occasionally enrich its meals with natural probiotics for dogs. 

Are Probiotics for Dogs Worth it?

Yes, probiotics for dogs are worth it. 

Probiotics for dogs promote gut health and intestinal motility, they improve the nutrient absorption and make poop scooping much easier.

They also help with issues such as bad breath and skin conditions. Based on the specific probiotic strains in the supplement they can even boost the immune function, thus supporting overall health.
